Pesticides are used in agriculture and in public health. Toxicity to humans include chronic and acute effects.. Therefore, knowledge of their concentration in drinking water treatment seems to be very important. The aim of this study was based on the literature indicating the presence of certain pesticides and pesticide metabolites in selected drinking water coming from the ground and deep-ground. The selected papers indicate that pesticides and metabolites of pesticides pollute water sources, underground water and deep-water. Concentrations of pesticides in most cases are lower than the 0.1μgl−1, which is the general limit concentrations of pesticides, and pesticides metabolites in drinking water.   Only in the case of the pesticide azinphos methyl was found overvaluation concentration of 3.22μgl−1, which realizes the necessity identification concentrations of pesticides and their metabolites in mineral and spring waters

  Vanadium, depending on the consumed dose may be toxic or health-promoting. Therefore, the knowledge of its concentration in the drinking therapeutic water, in particular in the medicinal mineral sources seems to be very important. This study was based on literature giving vanadium concentrations in some drinking waters derived from the ground and deep ground water.   The concentration of vanadium in ground water shown varies in the range from 1-138μgl−1. In volcanic regions of Italy vanadium concentration increases in relation to the water of a river as much as 100 fold. The concentration of vanadium in the mineral waters ranges from 1-93μgl−1. The problem of acceptable and desired concentration of vanadium in natural waters in the mineral remains open, but it seems that this concentration in the tested samples is not too high.
